1 In the drawings, 2 represents a frame, 3 the supporting-legs, and 4cutting-rolls mounted in bearingsin said frame, between which the paperor strawboard stock is fed from a roll 5 over a "table 6, said. roll andtable being supported by the frame 2 and legs 7. The rolls 4 areprovided with knives and creasers, which cut out the-blanks for theboxes, scor- Fig. 9 is a section. on the line .2 z of Fig. 12 is adetail of the folding deingor creasing them where the folds are to bemade at the corners of the loom-andas the blanks pass from between therolls they are delivered to the receiving mechanism of the pasting andfolding machine, as hereinafter described. These cutting devices formthe subject-matter of the'application of William B. Browning,filed-April 27, 1901, Serial No. 57,658, and need not, therefore, bedescribed in detail in this application. Theshaft 4 of the lowercutting-roll extends out beyond the frame on each side and is providedon one s end with a driven pulley 4 while its other end projects asuitable distance beyond the frame and is supported in a bearing 5 andprovided with a bevel-gear 5".

8 represents the frame of the pasting and folding machine, supported onsuitable legs 9 and having a flat top or table 10.

The pasting and folding machine is arr'angcdon the delivery side of thecuttingrolls longitudinally with respect thereto, and

the frame of said machine and the supports for said rolls may be unitedor arranged independently of each other, as preferred. Near the deliveryside of the cutting-rolls 1 provide two star-rolls, each consisting of ashaft 11, supported in bearings 12 transversely on the table 10, saidshafts being provided with a series of shallow longitudinal grooves 13to receive a corresponding number of flat plates or wings 14, that aresecured within said grooves by solder or other suitable means. Thestar-rolls are opposite the ends of the cutting-rolls and revolve in adirection substantially at right angles to the direction of rotation ofsaid cutting-rolls. As the blanks pass from between the cutting-rollsthe one in front will be pushed forward by those succeeding intoengagement with the star-rolls, its edges resting upon the oppositecorresponding wings of said rolls, being guided thereto by the plate 15.

In Fig. 11 I haveshown a blank lying upon the table and being ad vancedtoward the folding devices, a second blank on the point of beingdelivered upon the table by the starrolls, and a third blank that hasjust been delivered to said rolls from the cutting devices. Thestar-rolls have a step-by-step movement, and any suitable mechanism maybe provided for operating them. I prefer, however, to employ the meansshown clearly in Fig. 6 of the drawings, wherein 16 represents diskssecured on the shafts 11 and provided in their peripheries with a seriesof notches 17. A longitudinally-movable rod 18 is supported in astandard 19 on the top and adjustable in a slot 20 therein by means ofbolts 21. This rod is provided with a hook 22 at one end to engage thenotches of one of the disks 16, while an arm 23 near the opposite end ofsaid rod engages the notches of the other disk. A spring 24 normallyholds said hook and'arm in engagement with said disk. Mounted upon theshafts 11 are arms 25, pivotally connected to the rod 18 near its ends,each arm carrying a dog 26, adapted to engage, respectively, the notchesof said disks. Near each disk on the table 10 I provide pawls 27, alsoengaging, respectively, the notches of said disks. The rod is alsoprovided with a downwardly-turned end 28 in position to be struck by aroller 29, mounted in the side of the disk 30, that is secured upon theshaft 31. The revolution of said disk will cause the rod 18 to be movedlongitudinally against the tension of the spring to the positionindicated by dotted lines in Fig. 6. When the rod is moved, the hook 22and arm 23 will be disengaged from the disks and the dogs 26 will beadvanced one notch thereon, and on the return movement of said rod thedisks and the star-rolls will be revolved toward each other one step.The pawls 27 will slide over the disks as they are operated toward eachother, but will prevent any backward or reverse movement thereof. Whenthe rod 18 returns to its normal position, the hook and arm thereon willengage notches in the disks and prevent accidental movement of thestar-rolls. The tension of the spring 24 may be regulated by theadjustment of the arm 19.

32 is a rock-shaft mounted in brackets 33, carrying a knocker-arm 34 andthe arm 35, whose free end is held in engagement with the periphery ofthe disk by a spring 36. A notch 37 is provided in the periphery of saiddisk, into which the arm 35 drops with every revolution of the disk.When the arm drops off into the notch, the shaft will be rocked by thespring 36 and the knocker-arm will strike a shortquick blow on the blankand prevent it from buckling up'during its passage through thestar-rolls. The notch 37 is preferably near and in the rear of theroller 29, and as the rod 18 is operated to rotate the star-rolls onestep and discharge the blank the stroke of the knocker-arm willimmediately follow the movement of said rod and act upon the incomingblank and cause it to assume a level position in the rolls. Opposite theshaft 31, occupying a corresponding position beneath the top 10 andmounted in bearings in the machine-frame, is a shaft 38, and upon theseshafts 31 and 38 I provide sprockets 39 and 40, connected by belts 41,operating in depressions or grooves 42 in the top 10 and provided atintervals with a series of lugs 43, which project above said top duringa portion of their travel. The shaft 38 is provided with a sprocket 44,connected by a belt 45 with a sprocket 46 on a shaft 47, that is drivenfrom a gear 5 through a similar gear 48 on said shaft. When the blank isdischarged by the star-rolls, it falls upon the top 10 in position to beengaged by the lugs 43 and is moved thereby over the table or top intoengagement with the periphery of a paster-wheel 49, being directedthereon by a guide 50. This paster-wheel is pivoted on the wall of apaste-reservoir 51 by means of a screw 52. A ring of yielding material,such as rubber 49', is provided, preferably, within a groove in theperiphery of the paster-wheel.

The reservoir is preferably constructed of sheet metal, having ahopper-bottom and provided with supporting-rods 53, that are pivotallyconnected to the walls of the reservoir and have threaded upper endshung in slotted lugs 54 on the frame by means of thumb-nuts 55. (SeeFig. 6.) Upon loosening these nuts the rods may be swung out of theirsupporting-lugs when it is desired to disengage the reservoir from themachine. I also prefer to provide hooks 56, Fig. 10, on the reservoir toengage a rib 57 on the frame to prevent the reservoir from swingingoutward when the thumb-nuts are tightened. The

with a bearing 59 for a short shaft60,that

projects into the reservoir and whereon the sprocket 61 is secured. Astufiing-box 62 is preferably provided over the threaded outer end ofthe bearing 59 to prevent the escape of paste from the reservoir. Asprocket 63 is secured on the outer end of the shaft 60. The sprocket 61is connected by a chain 64 with idler-sprockets 65 and 66, supported onthe wall of the reservoir, the sprocket 66 being carried by a slottedplate 67, that is adjustable on a bolt 68 and by means of which thetension of the chain may be regulated. The sprockets 65 and 66 arearranged on each side of the wheel 49, and their upper edges are alittle above the lower edge of the said wheel, so that the chain 64 willengage the ring 49' and cause the wheel to revolve and at the sametimewill deposit a quantity of the paste material on said ring. I preferto employ a chain having flat links, which in passing through the pastewill gather up a considerable quantity and carry it up to thepastor-wheel. To prevent too great an accumulation of paste on the ringand to clean off any that may dry thereon, I prefer to provide a scraperdevice consisting of a plate69, having a slot 70 to receive the ring 49and mounted on a rod 71, that is longitudinally movable in a guide'72and in the wall of the reservoir. The rod 71 near the scraper ispreferably square in cross-section to fit the corresponding hole in said7 guide. The squared portion of the rod will prevent it and the scraperfrom turning and will insure the scraper being held evenly against theperiphery of the ring. The outer end of the rod is threaded and carriesa thumb-wheel 73, inclosed by a suitable cap 74. Rotation of'the wheel73 will move the rod 71 longitudinally and advance the scraper intoengagement with the ring 49 or withdraw it therefrom.

The operator can thus control the supply of paste on the pester-wheeland keep the periphery of the ring smooth and clear of all dried paste.The paste-feeding apparatus is driven by a belt 75, connecting thesprockets 63 with a sprocket 76 on the shaft 38. This shaft ishorizontally adjustable in slots 77 in the machine-frame by means ofslotted plates 78 and bolts 79. The adjustability of this shaft permitsproper tension of the belt and also of the carrier-belts 41. In Fig. 6 Ihave shown a box-blank in contact on one side with the periphery of thepastor-wheel.

This wheel, as shown, projects slightly above the plane of themachine-top, and when the blank comes in contact with the periphery ofsaid wheel its edge will bear thereon with sufficient pressure, beingheld down by the guide 50, to accumulate a considerable quantity ofpaste. During the passage of the blank over the pastor-wheel one edgewillbe coated with paste to secure the edges together when the blank isfolded. I prefer to provide gages 80, under which the blanks travel,that are supported upon rods 81, vertically adjustable in a transverseyoke 82.

These gages are raised or lowered to regulate their distance from themachine-top according to the thickness of paper-stock employed in makingthe boxes. The logs of the carrier-belts travel along beside these gagesand push the blanks beneaththern. As shown in Fig. 13, the gages for aportion of their length are provided with beveled or inclined upperfaces or surfaces 83, presenting comparatively thin outer edges overwhich the walls of the box are folded. WVhile one edge of the blank isbeing coated with paste its opposite edge engages the inclined surface84 of a folder 85, provided on the machinetop near the traveling belts.(See Figs. 11 and 13.) This folder turns the side of the blank as it iscarried along by the belts and is provided with an intermediate portion86, that approaches close to and runs parallel with the gage on thatside of the machine. The part 84 of the folder raises the blank on oneside to a substantially vertical position, as shown in Fig. 13, and whensoraised the blank travels along with one side held up by theintermediate portion 86. About the time the blank leaves the part 84 ofthe folder on one side it engages an inwardly-curved portion 88 of afolder 89, provided on the opposite side of the machine-top near thepastorwheel. As soon as the forward edge of the blank leaves the'wheel'it is engaged by this folder, and while the opposite side of the blankis traveling along by the part 86 the edge that is coated with paste isbeing raised to a vertical position bythe part 88, as indicated in Fig.13. The part 88 approaches the gage on that side of the machine, and acurved portion 90 of the folder crosses the gage and extends paralleltherewith toward the pressure-rolls. As the paste-coated side of theblank leaves the part 88 it is engaged by the curved portion 90 andfolded down over the flattened end 91 of the gage to the positionindicated in Fig. let. When the part 90 begins to fold down the pastededge of the blank, the part 92 of the opposite folder almostsimultaneously begins to fold down the blank on that side over thepasted edge. This part 92 crosses the gage and from thence runs paralleltherewith and with the folder on the opposite side toward thepressure-rolls. Upon leaving the part 92 the side ofthe blank will befolded over the end of the gage upon the paste-coated opposite edge ofthe blank.

(See Fig. 14.) I The outer ends of the folders are supported on rods 93,that are vertically adjustable in the yoke 92. By means of theseadjustable rods the distance between the folders and the machine-top maybe varied according to the thickness of the blanks and the pressure itis desired to exert upon them. "While the edge on one side of the blankis being coated with paste the opposite side will be raised to avertical position, and then the edge having been pasted it in turnwill-be raised and folded down to a horizontal position in advance ofthe other side,

so that when completely folded the pastecoated edge will be beneath andoverlapped by the opposite edge. As the folded blank passes out at thedischarge end of the folders it is engaged by the coacting pressurerolls93 and 94, the latter being carried on the shaft 47, that is mounted inboxes 95 on the machine-frame. The upper roll 93' is carried on a shaft96, that is mounted in boxes 97, that are arranged upon screws 98, whoselower ends rest upon the boxes 95 and whose upper ends project throughand are slidable in holes provided in plates 99 on said frame. Springs100 are provided between the boxes 97 and the plates 99 and normallyhold the upper roll down upon the lower with a yielding pressure andpermit it to adjust itself automatically to the thickness of the blanksthat pass between the rolls. The pressure-rolls squeeze the overlappingedges of the blanks together and spread the paste thereon, causing themto adhere firmly together. After leaving the pressure -rolls the blanks,that are now in the form of fiattened boxes with open ends, pass into aninclined chute 101, that directs them to a case 102, provided at thedischarge end of the machine. This case or box is supported upon a frame103 and has a table or floor 104 extende ing out for a considerabledistance beyond the machine and supported on legs 105. An opening 106 isprovided in the bottom of the chute 101, through which a packer-plate107 operates. arm 108, mounted ona crank-shaft 109, that is supported inthe frame 103] A link 110 has a pivotal connection with the arm 108 andalso with the frame 103. Preferably at a point near the table 104: Iprefer to provide springs 111 in the top and bottom of the case 102,between which and a suitable backingplate 112 the boxes, now in theirflattened form, are pressed together in a vertical position by thereciprocating movement of the packer. Any suitable means may be providedfor operating the packer-arm; but I prefer to provide a sprocket 113 onthe crankshaft 109, connecting the same with a' sprocket 114 on theshaft96 by a belt 115. Agear 116 on the shaft 96 meshes with a similar gearon the shaft 47 of the lower pressure-roll.

In Fig. l I have shown a counting device 117, by means of which thenumber of blanks delivered to the case may be registered. This device,however, I do not claim in this case, as the same forms thesubject-matter of a companion application which I am about to file.

The cutting and creasing rolls are preferably adapted to turn out twocompleted blanks with each revolution, and I therefore provide a gearmechanism for operating the star-rolls that will rotate them two stepswith each revolution of the cutting-rolls, so that as the blanks passout from the cutting-rolls they will move directly upon thesupportingwings of the star-rolls. The carrier-belts be- Thispacker-plate is carried by an neath the star-rolls are operated by therequired speed to present a pair of lugs beneath said rolls when a blankis on the point of being discharged therefrom. The star-rolls Will serveto regulate or control the feed of the blanks, preventing cloggingthereof and any delay in the operation of the machine. As soon as ablank has passed in toward the starrolls, it will be struck by theknocker-arm and any tendency of bending or buckling thereof arrested. Assoon as the blanks are caught by the lugs of the carrier-belts they willbe advanced toward the past-ing device, where one edge of each blankwill be coated with paste. At this point the blanks will be engaged bythe folder, their sides folded over, so.that the pasted and non-pastededges will overlap, and then these edges will be firmly pressed togetherby the pressure-rolls. The operation is thus continuous and complete. Aroll of paper or strawboard is fed in at one end of the machine, cutinto blanks of suitable size, pasted, folded, and discharged at theother end of the machine a complete box ready to be filled.
